WIGGINS, MS (WHLT) – We’re learning more about the first victim in a shooting which spread across the state Monday.

Amy Prentiss, the woman who police say was killed by her boyfriend (Shannon Lamb) in Gautier, MS before he traveled to Delta State University to kill a colleague, leaves behind one daughter.

Amy Prentiss’ ex-husband, Shawn O’steen, describes the relationship between Prentiss and their daughter Abigail as a close one. He says:

“Amy and Abigail were more like sisters than anything else.They did everything together, inseparable.”

After 7 years of marriage, O’steen remained close with Prentiss’ family, who still live in Wiggins – where he and prentiss met.

“Amy made an impact on everyone she met. She had a lot of friends in Ocean Springs, Gulfport, Pascagoula, who just loved her,” he says.

Monday morning when they received the call that she had been killed, Abigail remained strong. O’steen says her death wasn’t a big shock to the people who knew Prentiss’ relationship with the accused murderer.

O’steen tells our cameras what his daughter witnessed. He says:

“First he was extremely nice. He had a prescription drug addiction. and when he did not have the medication he reverted to a very paranoid, aggressive, abusive person.”

O’steen says on numerous occasions his daughter would ask him to pray for her mother’s safety.

“The community was robbed,” he says.

O’steen tells us there are plans to cremate Prentiss’ body and his daughter will spread her ashes across the earth.

Police have yet to confirm a motive in the death of Prentiss and Delta State professor Ethan Schmidt.
